4x6 Sonic Sampling

The 4x6 method is a well-established configuration that uses a 4 in. core barrel overcased with a 6 in. casing. Other sonic configurations follow in this manner with larger inner and outer casing sizes. When telescoping one casing over another, (such as 4x6) it is important to consider the spacing (annulus) between the telescoping casings. Geoprobe® sonic casing is designed so that each incremental casing is sized with bit clearances and annular space in mind.

The 8150LS is a full-size sonic rig that delivers big sonic power to the customer. Designed and built as a direct response to requests from large, multi-national companies, the new sonic rig can continuously sample and set casing in excess of 300 ft. (90 m) in a wide range of formations.

The Geoprobe® 8250LS Rotary Sonic joins the family of Geoprobe® sonic rigs. Currently in production drilling, the 8250LS runs 20-ft tooling and comes with many of the same features and options as the 8150LS.
